inactive for like 25 years ... but most of the rest of her family is still active. She specifically told me that to, say, attend weddings at the temple, you just have to be an active church member ... and that's pretty much it.
Her sister, her husband, their family ... often went to weddings at the temple and she and her husband were really not 'hard core'. They had their kids baptisms at the Church and went 'most Sundays' but weren't so devout that they like ... didn't let their kids swim on Sundays cause 'the devil owns the water on Sunday' ... unlike her brother's family. They also drank, alcohol AND coffee.
And I seriously doubt they paid 10% of their income to the Church. I also rather doubt that they were being reviewed and having to earn their 'Temple Card' every 2 years. Rather, they 'knew people who would vouch for them', and so they could go to Temple for 'happenings', if they were invited.
Maybe it varies on locale, and just generally 'who you know'. But I think that what you're talking about is a level of privilege that exceeds that of just being able to 'attend festivities at the Temple'.
What you're referring to is maybe the criteria for asking to actually be married ... at the Temple ... as opposed to just attending a wedding there.
